How to make your network's code
Type the network name
The SSID, exactly as it shows in the phone's list of networks. One stray capital and the code points at a network that does not exist.
Pick the security and the password
WPA/WPA2/WPA3 on almost every current router. If the network is hidden, tick the box — without it the phone will not go looking.
Download it in the format you will actually use
PNG for a screen or a chat. SVG if you are printing a sign, because it will not go blocky however large you make it.
A WiFi QR code is not a link. It is a line of text in a format phones have understood for years, carrying the network name, the security type and the password. The stock camera on an iPhone or an Android recognises that format and offers to join — no browser, nothing to install.
The detail that breaks most of these codes is the security type. If your router runs WPA2 and the code claims the network is open, the phone will try without a password and report that it cannot connect, without saying why. Choose WPA/WPA2/WPA3 unless your network genuinely has no password, and type the name exactly as it appears, capitals and spaces included.
Think about where the code will end up before you print it. The password rides inside it, so anyone who photographs the paper keeps it long after they have left. For a shop, an office or a short-term rental, generate the code for the guest network and keep the main one off the wall.
Remember too that the code is static — there is no server behind it to update. The day you change the router password, the sheet taped to the wall stops working and you need a new one. That is the same property that lets it work offline and never expire.
